Summary: This Tip provides information about the Tree Service Provider Registry and how to register your business. All tree service providers are required to be registered to conduct business in Seattle. Property owners are required to use registered providers and post a notice of major pruning or removal of trees at least three days before the work is done. If your business conducts removal or major pruning of trees 6 inches or greater on private property, or you provide consulting services to assess the condition of trees on private property, you will need to register your business.
